R-value measurements describe a material's resistance to heat transfer through conduction, convection, or radiation. It is often measured to ASTM C518, Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus. Element experts use a Heat Flow Meter to evaluate insulating materials themselves, or their performance in appliances and other products.
